“Remembering” emotional words is based on response bias,not recollection

Recent studies have demonstrated that emotional stimuli result in a higher proportion of recognized items that are “remembered” (e.g., Kensinger & Corkin, 2003; Ochsner, 2000), leading to greater estimates of recollection by the dual-process model (Yonelinas, 1994). This result suggests that recognition judgments to emotional stimuli depend on a recollection process. We challenge this conclusion with receiver operating characteristic (ROC) curve data from two experiments. In both experiments, subjects studied neutral and emotional words. During the recognition test, subjects made old-new confidence ratings as well as remember-know judgments. Four models of remember-know judgments were fit to individual subjects’ data: two versions of a one-dimensional signaldetection-based model (Donaldson, 1996; Wixted & Stretch, 2004), the dual-process model (Yonelinas, 1994), and the two-dimensional signal-detection-based model known as STREAK (Rotello, Macmillan, & Reeder, 2004). Consistent with the literature, we found that emotion increases subjective reports of “remembering.” However, our ROC analyses and modeling work reveal that the effect is due to response bias differences rather than sensitivity change or use of a high-threshold recollection process.     

La traviata and Oedipus

This paper explores the oedipal themes of Verdi's La Traviata, and proposes that it is his masterly treatment of their complexity which accounts for the psychological power of the opera. It is suggested that a particular quality of this opera lies in its ordinariness: no gross psychopathology is displayed, and yet it is mesmerizing. The claims of the eminent musicologist Joseph Kerman are explored that, in opera, music trumps words when there is a conflict between the apparent meanings of the libretto and the feel of the music, with special reference to the famous duet between Violetta (the ‘fallen woman’ – the traviata) – and her lover's father, Giorgio Germont, in which his harsh condemnation of her as conveyed by the libretto text seems to be softened, indeed quite altered, by the music. Other contradictions between the apparently explicit meaning of the text and the implicit sense of the music are also examined. These conflicts are illuminated by John Steiner's theory of two versions of the Oedipus situation, one paranoid–schizoid and the other depressive, which are contrasted with Grunberger's Oedipal views.     

Neural Computation and the Computational Theory of Cognition

We begin by distinguishing computationalism from a number of other theses that are sometimes conflated with it. We also distinguish between several important kinds of computation: computation in a generic sense, digital computation, and analog computation. Then, we defend a weak version of computationalism—neural processes are computations in the generic sense. After that, we reject on empirical grounds the common assimilation of neural computation to either analog or digital computation, concluding that neural computation is sui generis. Analog computation requires continuous signals; digital computation requires strings of digits. But current neuroscientific evidence indicates that typical neural signals, such as spike trains, are graded like continuous signals but are constituted by discrete functional elements (spikes); thus, typical neural signals are neither continuous signals nor strings of digits. It follows that neural computation is sui generis. Finally, we highlight three important consequences of a proper understanding of neural computation for the theory of cognition. First, understanding neural computation requires a specially designed mathematical theory (or theories) rather than the mathematical theories of analog or digital computation. Second, several popular views about neural computation turn out to be incorrect. Third, computational theories of cognition that rely on non‐neural notions of computation ought to be replaced or reinterpreted in terms of neural computation.     

Challenging ‘Belief’ and the Evangelical Bias: Student Christianity in English Universities

Abstract

Popular and academic accounts of university-based religion tend to privilege evangelical Christianity, presented as a morally conservative, conversionist movement at odds with university contexts, which are widely assumed to be vehicles for a progressive Western modernity. This is especially the case in the UK, given the association of higher education with secularisation, yet virtually no research has studied this interface by examining the lives of students. This article discusses findings from the three-year project “Christianity and the University Experience in Contemporary England”, including a nation-wide survey of undergraduate students, in examining how the experience of university shapes on-campus expressions of Christian identity. We argue that a sizeable constituency of undergraduates self-identify as ‘Christian’, but evangelicals emerge not as the dominant majority, but as a vocal minority. The emerging internal complexity is masked by a public discourse that conceives of religion in terms of propositional belief and presents evangelicalism as its pre-eminent form.     

The Establishment of Core Competencies for Canadian Genetic Counsellors: Validation of Practice Based Competencies

Numerous groups of health professionals have undertaken the task of defining core competencies for their profession. The goal of establishing core competencies is to have a defined standard for such professional needs as practice guidelines, training curricula, certification, continuing competency and re-entry to practice. In 2006, the Canadian Association of Genetic Counsellors (CAGC) recognized the need for uniform practice standards for the profession in Canada, given the rapid progress of genetic knowledge and technologies, the expanding practice of genetic counsellors and the increasing demand for services. We report here the process by which the CAGC Practice Based Competencies were developed and then validated via two survey cycles, the first within the CAGC membership, and the second with feedback from external stakeholders. These competencies were formally approved in 2012 and describe the integrated skills, attitudes and judgment that genetic counsellors in Canada require in order to perform the services and duties that fall within the practice of the profession responsibly, safely, effectively and ethically.     

Spiritual Coping in American Buddhists: An Exploratory Study

Researchers in the United States have examined spiritual coping in Christians, Jews, Hindus, and Muslims, but rarely Buddhists. Using qualitative methodology, the present study represents an initial investigation into Buddhist forms of coping. Twenty-four Buddhists from across the United States were interviewed by phone, examining how their spirituality is used to cope with stress. Thematic analyses revealed six forms of Buddhist coping—right understanding, meditation, mindfulness, spiritual struggles, morality, and finding support in one's sangha. Implications of the study are discussed, including possibilities for future research on Buddhist coping.     

Gender differences in mathematics anxiety: An artifact of response bias?

Abstract

Females are more likely than males to report anxiety about mathematics. Hunsley and Flessati (1988) examined two explanations for this difference: the sex-role socialization hypothesis, which states that gender differences occur as a result of differences in socialization, and the math experiences hypothesis, which states that math anxiety is due to previous experiences with mathematics, regardless of gender. They found support only for the math experiences hypothesis, and suggested that the gender difference in math anxiety may be an artifact of response bias.

The present study replicated the Hunsley and Flessati study and included an evaluation of response bias. One hundred and fifty Introductory Psychology students completed a series of questionnaires examining mathematics anxiety, attitudes and mathematical background. The findings of Hunsley and Flessati were replicated, however no evidence was found for a gender-linked response bias. An alternative explanation for the gender difference in math anxiety is proposed based on the finding that females are more self-critical.     

Understanding Linkages Among Mixture Models

The methodological literature on mixture modeling has rapidly expanded in the past 15 years, and mixture models are increasingly applied in practice. Nonetheless, this literature has historically been diffuse, with different notations, motivations, and parameterizations making mixture models appear disconnected. This pedagogical review facilitates an integrative understanding of mixture models. First, 5 prototypic mixture models are presented in a unified format with incremental complexity while highlighting their mutual reliance on familiar probability laws, common assumptions, and shared aspects of interpretation. Second, 2 recent extensions—hybrid mixtures and parallel-process mixtures—are discussed. Both relax a key assumption of classic mixture models but do so in different ways. Similarities in construction and interpretation among hybrid mixtures and among parallel-process mixtures are emphasized. Third, the combination of both extensions is motivated and illustrated by means of an example on oppositional defiant and depressive symptoms. By clarifying how existing mixture models relate and can be combined, this article bridges past and current developments and provides a foundation for understanding new developments.     

“What Are You?”: Racial Ambiguity,Stigma, and the Racial Formation Project

Using interview data from individuals who were frequently asked some version of the question “What are you?” in regards to their race, we apply a deviance perspective to frame these encounters as micro level racial formation projects. Racial formation projects are problematized when one’s race is not readily classifiable. These data suggest that when race is perceptibly ambiguous, stigma is assigned and normativity is enforced through discursive constraint and other means. Racially ambiguous individuals use many forms of resistance to navigate these encounters and make identity claims that either affirm or endanger the normative racial formation order.     

Psychology out of the laboratory: the challenge of violent extremism

The idea that people inevitably act in accordance with their self-interest on the basis of a calculation of costs and benefits does not constitute an adequate framework for understanding political acts of violence and self-sacrifice. Recent research suggests that a better understanding is needed of how sacred values and notions of self and group identity lead people to act in terms of principles rather than prospects when the two come into conflict. Perhaps the greatest challenge is to better understand how sacred causes and moral imperatives diffuse through a population and motivate some (usually small) segment of it to commit violent actions. The challenge to psychology is to adopt an interdisciplinary focus drawing on a range of research methods and to become bolder in its choices of study populations if it is to be relevant to real-world problems.
